Mathematical Undecidability, Quantum Nonlocality and the Question of the Existence of God, editor's comment page 2
I Introduction
1. Reality is intelligible and man’s knowledge and power limited
The title of the present book suggests that scientific results obtained in mathematics
and quantum physics can be in some way related to the question of the existence of
God. This seems possible to us, because it is our conviction that reality in all its
dimensions is intelligible. The really impressive progress in science and technology
demonstrates that we can trust our intellect, and that nature is not offering us a
collection of meaningless absurdities. Having achieved an amazing control over
nature man is tempted to declare that “hard” science (i.e. the knowledge about what is
observable and controllable) is the only reliable knowledge.1
It is remarkable, however, that present day science itself is inviting us to cross the
boundary of what we can observe and control, and to enter the domain of meta-
science. The same logic used in science seems to show also man's inherent limitations
in power and knowledge. And that is what we first of all intend to show with results
taken from mathematics and quantum physics:
 Mathematical Undecidability refers to the result that man will never have a
universal method to solve any mathematical problem. In arithmetic there always
will be unsolved, solvable problems.
 Quantum Nonlocality refers to the discovery that certain phenomena in nature seem
to imply the existence of correlations based on faster-than-light influences. These
influences, however, are not accessible to manipulation by man for use in, for
example, faster than light communication.
In the various contributions pieces of a puzzle are offered, which suggest that there
exists more than the world of phenomena around us. The results discussed point to
intelligent and unobservable causes governing the world. One is led to perceive the
shade of a reality which many people would call God. In order to avoid confusion it is
important from the very beginning to give a clear definition of what is meant by God
in the title of this book.
2. What is it that people call God?
When analyzing what people call God, one encounters in general two basic
elements. First, there is an event or phenomenon which one tries to understand, to
explain or eventually to control. Second, there is the awareness of one‟s own
fundamental limits of understanding and controlling that specific phenomenon. These
two elements lead people to think about the existence of God. It is in a certain sense
the application of the principle of causality: if there is an effect, then there should be a
cause. More specifically, if there is an effect which exceeds human knowledge and
power by a large amount, then there should be a cause superior to man. One may say
1
This attitude represents the positivistic form of skepticism. Already the founding fathers of
metaphysics, Plato and Aristotle, have been confronted with the skepticism of sophists, who denied
the possibility of finding the truth. Aristotle argued that the fundamental statement of philosophical
skepticism, that it is not possible to affirm anything truly, is already an absolute statement not
demonstrable by science. By accepting this statement as an absolute truth, one is therefore in
contradiction with its meaning. (cf. Aristotle, Metaphysics, Book XI - Part 5). Plato and Aristotle‟s
endeavor may encourage also present day men to search for truth beyond the observable and
controllable.

that the first idea of God is that of a being who knows also those things we don‟t
know and has the power to do things we cannot do.
This view appears very clear in a conversation between the physicists Paul Davies
and Richard Feynman. Referring to the laws of physics, Davies comments: at one time
people used to believe that God explained the universe. It seems now that these laws
of physics are almost playing the role of God - that they’re omnipotent and
omniscient. And Feynman answers: On the contrary. God was always invented to
explain mystery. God is always invented to explain those things that you do not
understand. Now when you finally discover how something works, you get some laws
which you’re taking away from God; you don’t need him anymore. But you need him
for the other mysteries... God is always associated with those things that you do not
understand. Therefore I don’t think the laws can be considered to be like God because
they have been figured out.2
The postulate that man will one day, by means of science, reach a complete
knowledge and control of nature and history was the heart of the materialistic
worldview which arose in the XIX century 3 and up to now has exerted great
influence. As Feynman suggests, the human mind is led to conclude the existence of
an omniscient and omnipotent being, because this is a necessary assumption to explain
those things that now are beyond human understanding and power. Consequently, if
one assumes that one day man will be capable of explaining all mysteries, then one
would not need God anymore. On the contrary, if it is possible to demonstrate that at
any time in the future there will be always things beyond human understanding -
mysteries - then one has to conclude that human knowledge and power is limited and
inferior to divine knowledge and power. Therefore, any position arguing that human
beings are capable, in principle, of reaching complete knowledge and control of the
world, becomes also a position arguing against the existence of God.
3. The classical proofs of the existence of God and the classical
criticism of these proofs
Any proof of the existence of God implicitly refers to unobservable causes moving
the world from beyond the realm of space and time, or assumes that there is an order
in the world that does not arise from the human mind. The first is, for instance, the
case of the proof of the unmoved mover that Aristotle gives in his Physics.4 He firstly
states that movement in a circle as observed in astronomy is eternal and then
concludes that there should be an eternal first unmoved mover who is the cause of the
movement of the heavenly bodies. As the basis for his proof Aristotle clearly searched
for a phenomenon that cannot be explained by a temporal chain of causes alone.5
However, the choice of the movement of the heavenly bodies was not a lucky one, as
the arrival of Galileo‟s and Newton‟s mechanics showed.
Thomas Aquinas, in his fifth way, states that the natural bodies lacking
intelligence move not fortuitously but towards an end, and concludes that some

intelligent being exists by whom these bodies are directed and governed.6 Paul Davies
reaches, on the basis of today‟s physics, basically the same conclusion, as he states
that the universe is a coherent rational and harmonious expression of a deep and
purposeful meaning.7 Notice that from the point of view of today‟s physics this
argument is stronger than that of movement by Aristotle: In his 5th way Aquinas takes
the appearance of correlations in nature as the very indication for the presence of
causality and consequently of a cause.
A drastic change in the appreciation of the classical proofs of the existence of God
could be observed after the discovery in the 16th century that the laws of nature are
written in a mathematical language. This discovery weakened the arguments of
Aristotle and Aquinas, at least when one adds the assumption that mathematical truth
is a man-made construction, and that behind the phenomena there is no physical
reality which escapes observation. On the basis of these assumptions one may
correctly conclude the following: If the cause of each phenomenon can be observed,
and what is observed can be described in terms of mathematical information
(algorithms or sequences of bits), and mathematics is a construction of the human
mind, then the laws behind the phenomena and even the phenomena themselves are a
man-made construction. Physical reality reduces to man-made virtual reality, and there
is no reason why we, human beings, will not actually know and control the future of
the world.
The postulates that the laws of nature originate from human modes of thinking,
and that every physical phenomenon can be explained by observable causes, are the
heart of Kant‟s criticism of the proofs of the existence of God.8 They are also
characteristic of the positions of Laplace and Comte.3 The summary of modern
atheism is this: If one considers thinking as an activity in which God does not play any
role at all, at the end one considers the exterior world as a domain in which God does
not play any role either. The belief that God is not present in the thinking methods
with which we become capable of mastering nature, is in practice widely accepted.
For many there is a separation and intellectual incompatibility between scientific
activities and religious life. The Dutch Nobel prize-winner, Simon van der Meer
expressed this as follows: As a physicist, you have to have a split personality to be
still able to believe in a god.9
4. The aim of this book
Without any doubt the discovery that the phenomena can be described in
mathematical terms has been of great benefit to the scientific, economic and cultural
development of mankind. The above mentioned assumptions, however, that
mathematics is a man-made construction and that observable things originate
exclusively from observable things, are not so obvious at all. In the field of philosophy
many arguments can be presented against it, but also new insight obtained in scientific
research gives evidence for its disputable character.
In this book, recent mathematical theorems are discussed, which show that man
never will reach complete mathematical knowledge. Also experimental evidence is

presented that physical reality will always partially remain veiled to man, inaccessible
to his control. It is intended to provide, in the various contributions, the pieces of a
puzzle which restore the possibility of a natural, intellectual access to the existence of
an omniscient and omnipotent being.
One should bear in mind, that the argumentation of this book is based exclusively
on noncontradictory thinking and observations from physical reality. When we
therefore consider God, it is the reality behind the phenomena which people assume
when they realize their fundamental limits in knowing and doing. But as said above,
this principle that explains the mysteries we cannot explain, is essential to the idea of
God as First Cause or First Mover, already encountered, for example, in pre-Christian
Greek philosophy.
In this use of the term God we do not necessarily include God as the Creator or first
temporal cause. In our opinion, the idea of Creation as a beginning of the world in
time is not something that appears to the mind as a necessary conclusion. In this
respect it is interesting to note that in most of Greek philosophy, including Aristotle,
the notion of a Creator is absent. Moreover, in the history of Christianity no formal
declaration has been given that it is possible to prove by rational means the beginning
of the world in time. Also philosophers like Aquinas, who delivered proofs of the
existence of God, denied the possibility of a rational demonstration of the beginning
of the world in time.10 Regarding the widely spread view of the Big Bang as the
beginning of the Universe, we would like to emphasize that scenarios for the very
early Universe have been proposed, in which the Big-Bang does not mark any
beginning but is an event occurring in time,11 or where the character of a singularity
has been removed.12
In comparison with the great monotheistic religions, the principle we refer to as
God or even the God of the philosophers is conceptually still quite undeveloped. It is
comparable to the notion of a Beethoven symphony for a person deaf from birth, who
knows musical theory and can read the score. He gets real knowledge, but misses
almost completely the full richness of the musical experience. Why then do we make
the effort and go through all of this detailed reasoning? It is because of an optimistic
vision on the capacities of human beings. Man with his intellectual effort is able to
know the existence of an unobservable reality, which he already encounters deep in
his heart. We think that the reflections presented in this book may contribute to
showing that science itself can become a road leading to God. And this may
undoubtedly promote the unity between man‟s scientific and professional activity, and
his religious life.

II Preface
On January 22, 1990, the late John Bell held at CERN (European Laboratory for
Particle Physics), Geneva a seminar organized by the Center of Quantum Philosophy,
that at this time was a association of scientists interested in the interpretation of
quantum mechanics. In this seminar Bell presented once again his famous theorem.
Thereafter a discussion took place in which not only physical but also highly
speculative epistemological and philosophical questions were vividly debated. The list
of topics included: assumption of free will in Bell‟s theorem, the understanding of
mind, the relationship between the mathematical and the physical world, the existence
of unobservable causes and the limits of human knowledge in mathematics and
physics.
Encouraged by this stimulating discussion some of the participants decided to
found an Institute for Interdisciplinary Studies (IIS) to promote philosophical and
interdisciplinary reflection on the advances of science. Meanwhile the IIS has
associated its activities with the Fondation du Léman, a Swiss foundation registered in
Geneva. With its activities the IIS intends to strengthen the unity between the
professional activities in science and the reflection on fundamental philosophical
questions. In addition the interdisciplinary approach is expected to give a contribution
to the progress of science and the socio-economic development. At present three
working groups are active within the IIS, i.e.:
- The Center for Quantum Philosophy
- The Wealth Creation and Sustainable Development Group
- The Neural Science Group
Since the talk by John Bell, and encouraged by him in those months before his
unexpected death, the Center for Quantum Philosophy of the IIS has organized a
number of seminars at CERN and promoted several symposiums and seminars in
collaboration with different European University Institutes and Foundations13,14.
During the holidays around the New Year of 1993 a group of scientists and University
students met in the Italian Alps for a symposium on Mathematical Undecidability,
Quantum Nonlocality and the Question of the Existence of God. Each day of this
meeting had its introductory lectures, followed by a vivid and informal discussion.
Being present at all presentations and discussions the editors could observe a more
than usual interest in the issues dealt with. Especially the manifold of disciplines
represented by the attendees, like philosophy, physics, chemistry, mathematics and
information science gave rise to unusual observations and remarks.
The unceasing interest in the discussion on the relationship between
Undecidability, Nonlocality and the Existence of God led the editors to the idea to
prepare the present publication based mainly on the contributions of the above
mentioned symposium. They are aware that the book cannot claim for any
completeness. The experience, however, of the vivid exchange of thoughts in the
different meetings justifies a preliminary summary of ideas. It is hoped that with this
edition further debates and discussions will be strongly stimulated.
The title chosen is intentionally quite provoking. How can mathematics and
quantum physics be brought in connection with God? The introductory chapter

intends to show the connection. The body of the book is distributed in three parts. The
first discusses the nature of mathematical knowledge, complexity and undecidability.
Thereafter physics and nonlocality plays a central role. At the end general aspects of
science and meta-science are dealt with and brought in relation with the existence of
God.
The block about mathematics starts with the contribution of Hans-Christian
Reichel, from the Institute of Mathematics of the University of Vienna, about the
recent developments in mathematics and the relation with the philosophy of
mathematics. He discusses several concepts, like meaning, exactness, chaos,
incompleteness, experimental mathematics, which ask for a deeper philosophical
reflection. Gregory J. Chaitin from IBM Research Division, New York, one of the
leading researchers on incompleteness and undecidability, explains why there are
fundamental limits to what we will ever be able to understand. Moreover he
establishes the somewhat astonishing parallelism between mathematics and statistical
mechanics, and associates Gödel‟s incompleteness theorem with quantum mechanics.
The next contribution is written by Filippo Cacace, an information scientist from the
University of Napoli, who examines the relation between undecidability and the
universality of a given mathematical problem. His analysis of the implications of the
Turing theorem corroborates the existence of limits in man‟s knowledge of physical
reality. Antoine Suarez, physicist and philosopher of the Institute for Interdisciplinary
Studies in Zurich, proves in a simple way that in arithmetic there always will be
solvable unsolved problems and raises the question whether such problems refer not
to the existence of a superior intelligence outside human mind. In any case, the
Kantian view that mathematics is an a priori mode of man‟s thinking has to be given
up. Juleon M. Schins, physicist from the University of Twente, finishes the first part
with a discussion of Roger Penrose‟s interpretation of the Gödel and Turing
theorems15.
The second part on physics and nonlocality starts with a contribution of F. Tito
Arecchi, Director of the National Optics Laboratory at the University of Florence. He
discusses the role of the three C's - catastrophe, chaos and complexity - for science
and includes philosophical considerations. Thereafter the transcript is given of the
above mentioned lecture by John Bell at CERN on indeterminism and nonlocality. It
includes also a selection of the informal one-hour discussion. In the following three
contributions, written by physicists, the arguments leading to the Bell inequalities are
further explained and an overview of experimental work is presented. Paul Pliska,
physicist of the Institute for Interdisciplinary Studies and patent attorney in Zurich,
explains in a for non-physicists understandable language the nonlocality theorems by
Bell, Greenberger-Horne-Zeilinger (GHZ), and Hardy. In addition he gives some
comments on the relationship between the principles of free experimentation and
nonlocality. Mark Fox from the Department of Physics in Oxford, reviews recent
experiments on nonlocality. He emphasizes that one should make a distinction
between Einstein‟s local-realistic view that rejects faster-than-light influences in
nature, and the realism that admits a physical reality that is not exclusively a
construction of the human mind. Antoine Suarez presents the principles of a nonlocal
causal model, in which one is not led to assume an absolute time or a universal order
of succession, and describes possible experiments where the prediction of this theory

would be in contrast to quantum mechanics. Juleon M. Schins finishes this section
with a discussion of the recent book of Bernard D'Espagnat on Veiled Reality16, who
in the context of quantum mechanics proposes an intermediary position between
conventional realism and radical idealism.
The third part of the book deals with several specific philosophical aspects and
draws some conclusions. Jacques Laeuffer, Expert-Engineer for G.E. Medical Systems
in Paris, discusses Laplace‟s and Comte‟s assumption that one day human beings will
enjoy an absolute and total knowledge of the world. He also includes an analysis of
the consequences of this scientistic or positivistic mentality for the knowledge of the
existence of God. What follows then is the Templeton Prize Address 1995 of Paul
Davies on Physics and the Mind of God, who asks the burning question, where do the
laws of physics come from? Arguments sustaining that these laws are our laws, not
originated by nature, he considers as arrant nonsense. in his view the universe is a
coherent, rational, elegant and harmonious expression of a deep and purposeful
meaning. Alfred Driessen, from the Department of Physics of the University of
Twente and member of the board of the IIS, evaluates the bestseller of Stephen
Hawking, A brief History of Time17, which is also a book about God...or perhaps
about the absence of God18. He asks whether the impossibility to demonstrate the
beginning of the world in time, as stated by Hawking, leads to the impossibility to
demonstrate the existence of God. The final remarks by Alfred Driessen and Antoine
Suarez summarize the main stream of argumentation in this book. By evaluations of
recent results in mathematics and physics man becomes aware of fundamental limits
in knowing and controlling reality. The plenitude and power of reality seems to
exceed the capacities humanity will ever possess. In this way science opens the road to
a reality which people in general call God.
The book would not be finished without the willingness of the different authors and
their contributions to the discussion, which helped to crystallize the ideas on this
highly fascinating subject. The authors would like to thank J.M. Schins and A. M. Fox
for their critical reading of some of the manuscripts. Kluwer Academic Publishers are
gratefully acknowledged for their interest and stimulation for this edition.

III Final remarks:
Becoming aware of our fundamental limits in knowing and
doing, implications for the question of the existence of God.
Having arrived at the end of this book the reader may not be completely
satisfied. He has read about mathematics, about physics and about the way others
think about science. But, so what? Why has this wide-ranging material been brought
together? Are there firm conclusions regarding what the title promises: the existence
of God? A comparison already mentioned in the Introduction could help answer these
questions. Consider the parts of a puzzle, representing in their totality a masterpiece of
art. The parts on their own are only small, colored pieces of cardboard. In this book
we tried to deliver some important pieces of that puzzle, indicated by the set of
questions. The reader should decide whether the pieces result in more than a random
distribution of colored pieces. Being optimistic the editors and probably others, will
see the vague but certainly discernible contours of a reality beyond the things we can
touch, see, hear, smell or taste. In any case, however, we are aware that we have not
reached completeness in solving our puzzle; some pieces are still missing that further
reflection should work out.
The first piece of the puzzle is supplied by mathematics. Turing and Gödel have
proved that in any formal (arithmetic) system one can formulate true statements,
which are undecidable within the formal system in question. As a consequence, each
formal arithmetic system lacks completeness. This means that man never can explore
the full richness of mathematics, not because of limitations in our time or ability, but
because of fundamental limits always present in any non-trivial formal system. The
undecidability and lack of completeness in formal systems also have consequences for
the origin of mathematical truth. The access of man to mathematical truth is
fundamentally incomplete. Mathematical truth, therefore, cannot be an exclusive
construction of the human mind.
The second piece of the puzzle, somewhat related to the foregoing, arises from
the experience of mathematicians of down the ages. There is information, knowledge
of abstract relations, which can be „discovered‟ by man, but which is not a product of
the human mind. In a certain sense the information discovered in mathematics at a
certain moment has always existed and will exist forever. It is reasonable to relate this
information to a reality, because information is something, it is not nothing. The
question then arises: who, or which principle, supports this information? The human
mind, with its limited access to mathematical information, surely cannot be considered
the only candidate.
Coming now to physics a new set of pieces of the puzzle can be found. Since
Laplace, and even before his time, the ideal of physics has been to find or derive a set
of equations, which allow a complete description of the reality accessible by the
methods of physics. In other words, physicists try to find a unique correspondence
between physical phenomena and representations in a formal system. This formal
system would permit, at least in principle, the calculation of all physical events. It is
obvious that enormous progress has been made in physics that has resulted in a
quantitative description of many physical effects. Nevertheless, the equations of
physics are at best a well-developed formal system. And regarding these systems
Gödel and Turing have proved that these can never be complete. There will therefore

10.
A.Driessen & A.Suarez, 1997
Mathematical Undecidability, Quantum Nonlocality and the Question of the Existence of God, editor's comment page 10
be physical events that cannot be adequately described by the formal system in
question. It is therefore an illusion to hope that physical reality can be perfectly
matched with a formal system, and therefore that physics can describe physical reality
completely. Physical reality always will be more than a set of equations.
The foregoing was an argument about an inherent shortcoming of any physical
theory based on a mathematical description of reality. And the “weak point” was in
mathematics rather than in physics itself. One could argue that physics could
somehow circumvent this problem. The questions now arise whether there are
fundamental limits to physics itself and whether physics can be considered to give a
complete description of the phenomena. The Einstein-Podolsky-Rosen paradox one
could consider as the next part of the puzzle we are trying to solve. The EPR paradox
- a two-particle gedanken experiment - and the consequent work by Bell, brings the
physicist face to face with nonlocal correlations. And nonlocality contradicts all
traditional physical theories. But things are more subtle. When we give a theoretical
description of EPR-like experiments using the relevant physical theory (in this case
Quantum Mechanics) we come up with results that are in complete agreement with
experiment. We should remark, however, that these theoretical predictions are
presented as probabilities that can be verified only by a large number of events. This
probabilistic description therefore seems to be a correct approach. Only if one
considers the single event, has one to assume unobservable causes which result in
nonlocality.
The apparent contradiction could be solved if one assumes a fundamental
incompleteness in physical theories. In some cases phenomena - or observable causes-
which obey physical laws, are not the only actors that take part in the realization of the
event. Other, unobservable actors that are not in contradiction with the statistical
nature of our physical theories seem to affect the single physical effect. Consider for
instance a quantum experiment in which the two output ports of a beam splitter are
monitored by detectors D1 and D2. The fact that one of two detectors clicks may be
explained by observable causes alone. But the particular alternative that D1 clicks and
D2 remains at rest, or conversely, cannot be explained by observable causes alone. In
general it can be stated that phenomena cannot be explained by a temporal chain of
causes consisting of other phenomena.
Also single particle events in nature, like a decay of a radioactive atom, seem to
demonstrate the lack of completeness in physical theories like Quantum Mechanics.
We can predict the decay rate with high precision, but we can say nothing about a
single atom, when it will decay. It is even less known why it decays in that certain
moment. The philosophically not so satisfying answer is that we may not ask these
questions or that it happens by chance. In the case of the EPR experiment (an essential
two-particle experiment) one has to give up the “chance” explanation. There is
experimental evidence of a correlation between the two particles even in the case of a
single event, which can not be the result of local hidden variables (Bell). Could it not
be possible that also in single particle events the “chance” theory should be given up
with the consequence of accepting the incompleteness of our physical theories?
With the pieces of the puzzle presented above, are we now in a position to come
to some conclusions about the total picture? The first could be that man, with his
formal approach in science, precisely due to this approach misses part of the
information contained in physical reality. The second is that man will never have
complete control over nature because in technology he uses exclusively physical

11.
A.Driessen & A.Suarez, 1997
Mathematical Undecidability, Quantum Nonlocality and the Question of the Existence of God, editor's comment page 11
observable causality. It seems that observable causes produce necessarily the expected
effect but are not sufficient causes for a particular event.
Is this a question of our present ignorance? Will a future generation of
mathematicians and scientists circumvent these difficulties? Or are we discovering
traces of a powerful actor or acting principle who, as the support of information, has
intelligence and is causing events in reality according to the physical laws? Certainly,
we will not return to former primitive times when people appealed to a supernatural
power in order to explain why the sun appears to go round the earth. But neither can
we claim that we do not need such a being any more, simply because with modern
science we now know considerably more about the reason why. And if we are obliged
to give up the position that science will enable man to master all mysteries, the road to
avoid absurdity may be the road that leads to a transcendent being. This is our third
tentative conclusion.
But does this not mean to return to the God-of-the-gaps, a cosmic magician
invoked to explain all those mysteries about nature that currently have the scientists
stumped, as P. Davies19 expresses? Is this not a dangerous position, as well? Probably
not, because we have evidence that the gaps in our knowledge and in our ability to
determine events are structural. It is not a question of knowing or doing more or less.
In a certain sense nature can be considered to be a miracle, as Davies himself states,
because natural phenomena have unobservable causes beyond the reach of any human
power. There always will be unsolved mathematical problems, and we have to live
with nonlocality.
Finally, we would like to comment on an apparently paradoxical situation. Modern
science which accepts man‟s fundamental limits in knowing and doing, comes out to
be more efficient than the science which believed that man will some day be able to
know all. Now, when we have given up the postulate of absolute predictability, we
predict and control better as ever before. We become capable of doing more and more
marvelous things just because we have accepted that we will never be able to do
everything.
Looking back now at the present book, we surely have not given a complete answer
to all of the problems related to the title. Some results have been presented and
conclusions have been given. One should bear in mind, however, that science is not
the only access to reality. The rich world of human feelings and thoughts as expressed,
for example, in literature, art, humanities and also in conversations in daily life,
provides alternative routes to reality in all its dimensions. Could it be that the
intelligent and powerful actor, whose outline, after much effort, seems becoming
visible to the scientist, is identical with what people call God?
